Materials Data on NaSbCl6 by Materials Project
NaSbCl6 crystallizes in the tetragonal P4_2/m space group. The structure is three-dimensional. Na1+ is bonded in a 8-coordinate geometry to eight Cl1- atoms. There are four shorter (2.90 Å) and four longer (3.34 Å) Na–Cl bond lengths. Sb5+ is bonded in an octahedral geometry to six Cl1- atoms. There are two shorter (2.41 Å) and four longer (2.42 Å) Sb–Cl bond lengths. There are two inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in a water-like geometry to one Na1+ and one Sb5+ atom. In the second Cl1- site, Cl1- is bonded in a 1-coordinate geometry to two equivalent Na1+ and one Sb5+ atom.
